Bug#298492: mifluz: FTBFS (amd64/gcc-4.0): cast from 'char*' to 'int' loses precision

[Andreas Jochens]

Package: mifluz
Severity: normal
Tags: patch

When building 'mifluz' on amd64 with gcc-4.0,
I get the following error:

rm -f .libs/WordDB.lo
g++ -DHAVE_CONFIG_H -I. -I. -I.. -DCONFIG_FILE=\"/etc/mifluz/mifluz.conf\"

WordDBCache.h:153: error: cast from 'char*' to 'int' loses precision
make[3]: *** [WordDB.lo] Error 1
make[3]: Leaving directory `/mifluz-0.24.0/mifluz'

With the attached patch 'mifluz' can be compiled
on amd64 using gcc-4.0.
